Kaluza-Klein Gravity, Concentrating on the General Rel- Ativity, Rather Than Particle Physics Side of the Subject
Kaluza-Klein Gravity J. M. Overduin Department of Physics and Astronomy, University of Victoria, P.O. Box 3055, Victoria, British Columbia, Canada, V8W 3P6 and P. S. Wesson Department of Physics, University of Waterloo, Ontario, Canada N2L 3G1 and Gravity Probe-B, Hansen Physics Laboratories, Stanford University, Stanford, California, U.S.A. 94305 Abstract We review higher-dimensional unified theories from the general relativity, rather than the particle physics side. Three distinct approaches to the subject are identi- fied and contrasted: compactified, projective and noncompactified. We discuss the cosmological and astrophysical implications of extra dimensions, and conclude that none of the three approaches can be ruled out on observational grounds at the present time. arXiv:gr-qc/9805018v1 7 May 1998 Preprint submitted to Elsevier Preprint 3 February 2008 1 Introduction Kaluza’s [1] achievement was to show that five-dimensional general relativity contains both Einstein’s four-dimensional theory of gravity and Maxwell’s the- ory of electromagnetism. He however imposed a somewhat artificial restriction (the cylinder condition) on the coordinates, essentially barring the fifth one a priori from making a direct appearance in the laws of physics. Klein’s [2] con- tribution was to make this restriction less artificial by suggesting a plausible physical basis for it in compactification of the fifth dimension. This idea was enthusiastically received by unified-field theorists, and when the time came to include the strong and weak forces by extending Kaluza’s mechanism to higher dimensions, it was assumed that these too would be compact. This line of thinking has led through eleven-dimensional supergravity theories in the 1980s to the current favorite contenders for a possible “theory of everything,” ten-dimensional superstrings. -
New Pad Constructed for Smaller Rocket Launches
PROGRAM HIGHLIGHTS • JULY 2015 At NASA’s Kennedy Space Center in Florida, the Ground Systems Development and Operations (GSDO) Program Office is leading the center’s transfor- mation from a historically government-only launch complex to a spaceport bustling with activity involving government and commercial vehicles alike. GSDO is tasked with developing and using the complex equipment required to safely handle a variety of rockets and spacecraft during assembly, transport and launch. For more information about GSDO accomplishments happening around the center, visit http://go.nasa.gov/groundsystems. New Pad Constructed for Smaller Rocket Launches NASA's Kennedy Space Center in Florida took another step forward in its transformation to a 21st century multi-user spaceport with the completion of the new Small Class Vehicle Launch Pad, designated 39C, in the Launch Pad 39B area. This designated pad to test smaller rockets will make it more affordable for smaller aerospace companies to develop and launch from the center, and to break into the commercial spaceflight market. Kennedy Director Bob Cabana and representatives from the Ground Systems Development and Operations (GSDO) Program and the Center Planning and Development (CPD) and Engineering Directorates marked the completion of the new pad during a ribbon-cutting ceremony July 17. NASA Kennedy Space Center Director Bob Cabana, center, helps cut the ribbon on the new Small Class Vehicle Launch Pad, designated 39C, at Kennedy Space Center in Florida. Also helping to cut the ribbon are, from left, Pat Simpkins, director, Engineering and Technology Directorate; Rich Koller, senior vice president of design firm Jones Edmunds; Scott Col- loredo, director, Center Planning and Development; and Michelle Shoultz, president of Frazier Engineering. -

Space Launch System (Sls) Motors
Propulsion Products Catalog SPACE LAUNCH SYSTEM (SLS) MOTORS For NASA’s Space Launch System (SLS), Northrop Grumman manufactures the five-segment SLS heavy- lift boosters, the booster separation motors (BSM), and the Launch Abort System’s (LAS) launch abort motor and attitude control motor. The SLS five-segment booster is the largest solid rocket motor ever built for flight. The SLS booster shares some design heritage with flight-proven four-segment space shuttle reusable solid rocket motors (RSRM), but generates 20 percent greater average thrust and 24 percent greater total impulse. While space shuttle RSRM production has ended, sustained booster production for SLS helps provide cost savings and access to reliable material sources. Designed to push the spent RSRMs safely away from the space shuttle, Northrop Grumman BSMs were rigorously qualified for human space flight and successfully used on the last fifteen space shuttle missions. These same motors are a critical part of NASA’s SLS. Four BSMs are installed in the forward frustum of each five-segment booster and four are installed in the aft skirt, for a total of 16 BSMs per launch. The launch abort motor is an integral part of NASA’s LAS. The LAS is designed to safely pull the Orion crew module away from the SLS launch vehicle in the event of an emergency on the launch pad or during ascent. Northrop Grumman is on contract to Lockheed Martin to build the abort motor and attitude control motor—Lockheed is the prime contractor for building the Orion Multi-Purpose Crew Vehicle designed for use on NASA’s SLS. -

SHUTTLE-C HEAVY-LIFT VEHICLE OF THE 90 ' S Mr. Robert G. Eudy, Manager Shuttle-C Task Team Marshall Space Flight Center ABSTRACT United States current and planned space activities identify the need for increased payload capacity and unmanned flight to complement the existing Shuttle. To meet this challenge the National Aeronautics and Space Administration is defining an unmanned cargo version of the Shuttle that can give the nation early heavy-lift capability. Called Shuttle-C, this unmanned vehicle is a natural, low-cost evolution of the current Space Shuttle that can be flying 100,000 to 170,000 pound payloads by late 1994. At the core of Shuttle-C design philosophy is the principle of evolvement from the United State's Space Transportation System. -
